AIR-TIGHT STOVE.

Specification of Letters Patent No. 5,158, dated June 19, 1847.

To all whom it may concern:

Be it known that I, SAMUEL B. SEX'roN, of the city of Baltimore and State of Maryland, have invented certain new and useful' Improvements in Air-Tight Stoves which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

The nature of my invention and improVe-' ment consists in a certain new and useful combination of a ventilator in connection with a register united by a rod in such a manner that when the register is closed the ventilator is opened in the same proportion. Also a new arrangement of a horizontal tapered flue or tube in connection with the ventilator and smoke pipe for the combined purpose of ventilating the room, and having the same pipe to be a safety flue against puffs, or explosions caused by the current of air forced down the chimney into the stove, and likewise for preventing puffs caused by the sudden opening'or closing of the door of a close room in which the stove is placed.

The object of the ventilator and tube or ipe is to keep up a circulation of air in the room at all times without the loss of too much heat and to cause the oppressive bad air to pass out of the room through the stove into the chimney without disturbing or agitating the fire and at the same time renders the stove free from explosion or puffs, from slamming of doors or currents down chimney.

Figure 1 is a perspective view of the stove. Fig. 2 is a vertical section through the cen ter of ditto. Similar letters in the several figures refer to corresponding parts.

First, I make a stove A in the ordinary way with a door H at the end, or. other convenient place for the introduction of the wood. About 3 inches from the bottom I place in front of the stove a register B of circular form, or of any other form, that will suit best. I then place one of similar size and form about the same distance from the top which I term a ventilator: this is let-' tered C. A rod D leading from the register to the ventilator connects them together by inserting the ends of said rod D into'loops or staples I J riveted to the register and ventilator. This rod D turns on a pivot E in the center of said rod, fastened to the center of the front of the stove. By moving the ventilator the rod is moved which" moves the register in the same pro ortion: thus as the stove becomes hot, We 0 ose the register B and at the same time open the ventilator C. W I

.On the inside of the ventilator I place a tapered tube F of suflicient size (at the smaller end) to ventilate the room. The small end enters the smoke pipe or collar G, which is made larger to allow the smoke to pass to .the chimney through the annular space around theventilator tube. The lar e end of the ventilator tube that covers t e dled in regulating the draft without burning the hand although the stove in other places may be quite hot. i

This ventilator in'the stove'makes what may be termed a safety valve; for whenthe air is forced down the chimney instead of going into the chamber of combustion it passes through the ventilator tube into the room without doing any harm; and the cur rent of cold air that passes through the venloops, or staples, are made in the usual manner, of a rectangular or other form; and riveted to the registerB and ventilator C one to each. Or instead thereof, oblongmortises may be made in the ends of the rod D through which connecting pins with loops or staples in which I the ends of the vibrating rod D play. These 7 broad flat heads, are insertedbeing riveted *to the ventilator and register-the oblong mo-rtises being of sufficient length to allow the requisite play of the rod D as the B and C are turned.

What I claim as my invention and im plates H provement and desire to secure by Letters Patent is The manner of combining the ventilator ,C with the register B by means of the viinto the loops" I, J, and turning on the cenf tral pivot E, for the purposes above stated.
